Probably the same one I had. The Star Trek TNG Technical Manual. Which seems to still be in print somehow.
I just checked. It talks about omnidirectional holographic diodes acting like a fly’s eye in reverse. And that they emit interference patterns that converge “at the lens of the eye or other visual receptor.” So according to the technical manual, they were doing eye tracking and projecting images directly into them at the right perspective.
There’s a diagram with the caption “Substrate forcefield creates ‘treadmill’ effect, permitting participant to remain stationary while the simulated environment ‘scrolls’ by, within the limits of the simulation program”
If it can deal with whatever weird alien vision systems come into it, it must be able to deal with Geordi’s hairband…I mean visor.
